INIPRQVBMENT IN'. ROSES FOR DOOR-KNOBS.

The Schedule referred to in these Letters Patent and making part of che same.

To all whom 'it may concern:

Be it known that I, CHARLES L. BATES, of New York city, in the county and State of New York, have invented a new and useful Improvement in Mounting the Porcelain Rose for Door-Knobs; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

Figure l is a central cross-section of my improved porcelain rose for door-knobs, taken through the line a: x, fig. 2.

Figure 2 is a face view of the same.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improvement in mounting the porcelain rose of doorknobs, by means of which they may be more securely and durably secured in place, and may not be liable to become loose; and

It consists of the rose and plate, constructed and combined with each other, as hereinafter more fully described.

A represents the porcelain rose, the outer surface of which is made dat, with a rise iu its centre around the orice that receives the socket B of the knob-shank.

The porcelain rose A is moulded with two or more holes through its flat part, to receive the sockets for the attaching-screws to pass through.

C is the plate, which tits into a recess formed in the inner side of the rose A.

The plate O is formed with two or more perforated projections upon its outer side, which pass through and t into the holes through the flat portion of the rose A, as shown in iigs. 1 and 2.

The socket B is formed with a ilange around its outer end, which overlaps' the edge 0f the rose A, as shown in fig. 1.

The edge of the inner end of the socket B is turned down over or riveted upon or to the plate C, as shown in fig. 2, so that the rose may be conveniently and firmly secured in place by screws passing through the perforated projections of' the plate C, and screwing into the door to which the knob is to he attached.

By this construction the porcelain rose is iirmly and durably scoured in place, by screws passing through said rose, in such a way as not to come in contact with the porcelain, and thus, are in no danger of breaking or injuring the said rose.

Having thus described my invention,

XVhat I claim as new, and desire to secure by Letters Patent, is-

The plate C, provided with .the hollow projections e.:tendiug through the porcelain rose Aandthe shanksocket B, holding the plate C and rose A together, al1 arranged as described, for the purpose specified.

The above specification of my invention signed by me, this 24th day of February, 1869.

CHARLES L. BATES.
